git push 提交代码报错 WARNING: REMOTE HOST IDENTIFICATION HAS CHANGED!

个人项目遇到的问题，几天没提交代码了，今天做了些优化，准备提交到 github 时出现了问题，错误提示信息如下：

PS D:\workspace\qianduan.shop> git push
@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@
@    WARNING: REMOTE HOST IDENTIFICATION HAS CHANGED!     @
@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@
IT IS POSSIBLE THAT SOMEONE IS DOING SOMETHING NASTY!
Someone could be eavesdropping on you right now (man-in-the-middle attack)!
It is also possible that a host key has just been changed.
The fingerprint for the RSA key sent by the remote host is
SHA256:uNiVztksCsDhcc0u9e8*****************.
Please contact your system administrator.
Add correct host key in /c/Users/admin/.ssh/known_hosts to get rid of this message.
Offending RSA key in /c/Users/admin/.ssh/known_hosts:2
RSA host key for github.com has changed and you have requested strict checking.
Host key verification failed.
fatal: Could not read from remote repository.

Please make sure you have the correct access rights
and the repository exists.

如何解决

通过分析错误提示，发现远程主机发送的SHA256值与之前存放于/.ssh/known_hosts不一致，通过删除known_hosts解决。

还有个简单的办法，执行 ssh-keygen -R gitHub.com 命令即可：

C:\Users\admin>ssh-keygen -R github.com
Host github.com found: line 2
C:\Users\admin/.ssh/known_hosts updated.
Original contents retained as C:\Users\admin/.ssh/known_hosts.old

然后再次 git push 推送代码:

PS D:\workspace\qianduan.shop> git push
The authenticity of host 'github.com (20.205.243.166)' can't be established.
ECDSA key fingerprint is SHA256:p2QAMXNIC1TJYWeIOttrVc98/R1BUFWu3/LiyKgUfQM.
